What is a NOAA tide table?

This image shows daily tide predictions for Eastport, Maine, for January-February 1867. This page is from the first edition of a national annual tide table publication created in 1866 by the U.S. Coast Survey, a predecessor of NOAA.

A tide table provides daily high and low tide predictions. NOAA tide tables are available for more than 3,000 locations around the nation. NOAA’s Center for Operational Oceanographic Products and Services and predecessor agencies have produced tide tables for more than 150 years.

Tide tables are different from tide charts. A tide chart shows water levels on an hourly basis after high tide throughout a bay or an estuary at a particular point in time. Such charts are only available for a few locations around the nation.
